SSL VPN and Port Forwarding - Cisco Community Port forwarding is the legacy technology for supporting TCP-based applications over a clientless SSL VPN connection. You may choose to use port forwarding because you have built earlier configurations that support this technology. Please consider the following alternatives to port forwarding: What ports should be open on my firewall to allow the TCP port 636 -- LDAPS: SSL secured LDAP TCP port 3268 -- LDAP: Active Directory Global Catalog TCP port 3269 -- LDAPS: SSL secured Active Directory Global Catalog.

However, if the FTP control connection is encrypted using TLS/SSL, the firewall cannot determine the TCP port number of a data connection negotiated between the client and FTP server. Therefore, in many firewalled networks, an FTPS deployment will fail when an unencrypted FTP deployment will work, but this problem can be solved with the use of
